Well it is beyond adding a torpedo mount - it is a matter of 3D modelling. Unlike low-level ships like the DDs, which have torpedo mounts on the deck, a ship like the Mogami has holes in the side of its superstructure to operate them. Thus, if indeed Mogami is supposed to have Starboard torpedoes mounts too (something I couldn't clarify yet, but nothing in its log available at Combined Fleet website indicate any torpedo mount removal) the whole 3D model will have to be addressed...

Still I can live with that
